Lamellae in Alpin Soil
Lamellae are thin, often discontinuous layers of clay-enriched material that are associated with iron oxides and may occur in Alfisols, Ultisols, Mollisols, Entisols, Inceptisols, or Spodosols. These soils are of small extent in the Southeastern United States. The natural vegetation consisted of forest plants. These soils generally are nearly level or gently sloping. They are used mostly as forest or cropland. Some are used as pasture or homesites.
The Alpin series consists of very deep, excessively drained, moderately rapidly permeable soils on uplands and river terraces of the Coastal Plain. They formed in thick beds of sandy eolian or marine deposits. Near the type location, the mean annual precipitation is about 55 inches and the mean annual temperature is about 68 70 degrees F. Slopes range from 0 to 15 percent.
TAXONOMIC CLASS: Thermic, coated Lamellic Quartzipsamments
RANGE IN CHARACTERISTICS: Thickness of sand is 80 inches or more. Reaction ranges from very strongly acid to slightly acid throughout. Depth to lamellae ranges from 40 to 78 inches but most commonly is 50 to 70 inches. Cumulative thickness of lamellae ranges from 1 cm to 15 cm.
